3M 90542H1-DC-PS Worktunes Bluetooth Hearing Protector 3 Pack

Product Description

The 3M 90542H1-DC-PS is a Bluetooth-enabled hearing protector earmuff designed for trade and industrial environments where both hearing protection and audio access are needed on the job. The unit streams audio from Bluetooth-enabled devices including mobile phones, tablets, and media players directly to the earmuff, allowing the user to receive audio without removing hearing protection. This package contains 3 units, making it a practical choice for crews or multi-technician supply orders. It is a self-contained, over-ear design requiring no secondary earbuds or adapters. HVAC techs, electricians, plumbers, and other trade professionals who work in high-noise environments are the primary installers and end users.

The 90542H1-DC-PS is suited for residential and commercial job sites where sustained noise exposure from equipment such as compressors, generators, saws, or HVAC systems requires hearing protection under OSHA noise standards. The earmuff form factor provides a passive barrier while the integrated Bluetooth receiver handles audio streaming. This 3-unit package is appropriate for supply houses, fleet orders, or multi-person crews needing consistent PPE across a job site.

Installation Notes

Hearing protectors do not require installation in the traditional trade sense, but proper fit and seal are critical to achieving rated noise attenuation. Inspect the cushion seal before each use for cracks or deformation that would reduce protection. Follow OSHA 29 CFR 1910.95 guidelines for hearing conservation programs when deploying PPE in sustained high-noise environments. Replace units showing physical wear to cushion seals, headband tension, or electronic components that affect performance.
